For many, being proactive with chiller maintenance in the early winter has led to better results in the spring, when it’s time to start the systems up again. Performing chiller maintenance as early in the winter as possible gives facility managers the benefit of finding major damage with plenty of time to fix the problems before the chiller needs to be back in operation.
Bob and Tim are driving to a new customer site where there is a complaint of the building not maintaining the correct temperature. The system is a 50-ton air cooled chiller mounted on the roof. The weather is very hot, 97°F, and the indoor conditions are 78°F. The thermostat is set for 75°, and it is late afternoon.
Bob and Tim are at lunch and discussing the last service call that they had which was a spring start up on a 100 ton chiller. Tim has some questions about how a chiller operates and Bob is filling him in on some blank places that he has in his knowledge base.
There have been numerous studies that have shown regular maintenance extends the life of HVAC equipment, and chillers are no exception to that rule. But unfortunately, many building owners and facility managers defer maintenance due to budgetary constraints or other reasons, which can lead to performance issues later down the road.
A new Center for Disease Control and Prevention (CDC) study involving 196 cooling towers nationwide found that 84 percent contained Legionella DNA, indicating that the dangerous bacteria that causes a severe, even fatal type of pneumonia were present or had been at some point.

US Chiller Services, provider of repair, maintenance, retrofit, and servicing of large tonnage chillers, has entered into a joint venture with New York-based HVAC specialist, The BP Group, to offer a full range of HVAC services for large tonnage chillers and equipment to an expanded client portfolio in the New York tri-state area.
Performing regular maintenance on chillers ensures they will operate as efficiently, and for as long, as possible. And while maintenance plans and practices can vary from region to region, manufacturer to manufacturer, and even client to client, HVACR contractors agree that minimal maintenance is better than no maintenance.
Bob and Tim were getting set up to clean the condenser tubes in a chiller. They were doing this job at night during overtime hours because they discovered the problem earlier that afternoon and the customer said the chiller needed to be able to operate at full capacity tomorrow for a conference.
Bob and Tim were on their way to a no cooling call at an office building with a 100-ton water-cooled chiller. As always, management was in a hurry to get the problem solved because the tenants were hot.
